Abstract

This data gives the concentration of nutrients in sea water samples from the water column and from sediments (pore-water) from the North Sea and English Channel. Includes measurements for Total Oxidised Nitrogen (TOxN) Nitrite (NO2) Phophate (P04) Silicon (Si) and Ammonia (NH4)

Lineage

Samples from the water column were collected by Niskin bottles deployed on a 'CTD rosette'. Pore-water is the sea water held in the pore-spaces of marine sediments and was sampled using by a sipper system from 11 depth horizons in undisturbed sediment cores collected by a NIOZ box corer. Resulting water samples were filtered and analysed using a Skalar nutrient analyser.This data is used to determine where and how organic matter is decaying, as well as analysing sediment linkage to macronutrient cycles (N, P, Si) via nutrient fluxes or uptake across the sediment-water interface. Samples were collected in the English and Dutch sectors of the Greater North Sea during three cruises on RV Cefas Endeavour (Cruise Codes CEND 15/09, CEND 11/10 and CEND 11/11) Records include data from Defra funded project ME5301 entitled "Mapping the structure, function and sensitivity of seabed sediment habitats to support assessment of the sea-floor status and the broadscale monitoring and management of the benthic environment" which sampled locations in the North Sea and western English Channel.
